SWIVEL HINGE SUPPORT Filed May 5, 1960 INVENTOR HENRY J. GARIEPYATTORNEY This invention relates to a new and improved swivel hingesupport embodying the well known swivel base comprising a pair of platesswiveled centrally together and having interposed ball hearings or thelike, in combination with upstanding supporting means at thediametrically opposite edges of said plates, said supporting meanscomprising essentially a pair of springs and in some cases interpivotedleaves or ears supporting in spaced relation to said swivel base atilting plate which in turn may serve for a support for an object whichis to be swivelly and tiltably mounted such as a chair seat or the like,the leaves or ears providing a fixed axis of tilting action for thetilting plate.

Further objects of the invention include the provision of a swivel hingsupport as above stated including a hinge construction, said hinge beingan elongated U-shaped spring member, a sliding tubular support on oneplate and a rotating boss-like support on the other plate, said supportsreceiving the respective ends of said U-shaped spring member, the rotarysupport being provided with means for clamping the respective leg of theU-shaped spring member thereto, the result being that the spring itselfacts as a support for the tilting plate and the same is tilted with abodily motion on an indeterminate axis.

The invention further relates to arrangements and combinations of partswhich will be hereinafter described and more particularly set forth inthe appended claims.

Reference is to be had to the accompanying drawings, in which:

FIG. 1 is a view in side elevation illustrating one form of theinvention;

FIG. 2 is a similar view illustrating the other form of the invention;

FIG. 3 is a view in front elevation, looking in the direction of arrow 3in FIG. 1; and

FIG. 4 is a plan view, looking in the direction of arrow 4 in FIG. 1.

In carrying out the present invention, I utilize a conventional swivelbase generally indicated by the reference numeral 1%. This swivel baseis the same as that indicated by the reference numeral 12 in FIG. 2. Ingeneral, this base comprises a pair of pressed plates with swivel meansat the center thereof as at 14 in FIG. 1 or 16 in FIG. 2. The swivel maycomprise a large hollow rivet or the like but in any event the twoplates comprising the respective swivel plates and 12 are swivellymounted one on the other and there may be interposed ball bearings orthe like which are generally indicated at 17.

In the case of FIG. 1, at diametric points on the upper one of theswivel plates 10 I provide upstanding ears 2% 22 which may be welded orotherwise secured thereto by inturned legs or the like 24, 26. There isa tilting plate generally indicated at 28 and at the diametricalopposite edges thereof this is provided with like plates or brackets36*, 32 which are pivotally mounted on the ears 2% and 22 by pins 34 orthe like, the pins 34 being diametrically aligned and forming an axisfor the tilting ac- 3,970,343 Patented Dec. 25, 1962 tion of plate 28 onswivel base 10 as indicated by the arrow which is indicated at 36 inFIG. 1.

Welded or otherwise secured to the swivel plate 2.8 there are a pair ofdiametrically opposite tangentially mounted tubular members 40, 42 andmounted on the plate 10 there are a pair of diametrically opposingswivelling bosses 44, 46. The bosses are apertured to receive the legs48, 5d of U-shaped springs 52 and the tubular members slidably receivethe legs 54 and 56 which form the opposite terminal portions of thesprings 52. It is to be noted that the legs 54 and 56 are slidablyreceived diametrically of the bosses 44 and 4-6 and setscrews at 58 areprovided to secure the legs 48 and 50 in their respective bosses inadjusted position therein. At the same time, the legs 54 and 56 areslidably arranged in the tubular members 40 and 42, and if desired thepositions of the springs can be easily changed to bring the closed endsof the springs closer to or farther from the axis of pins 34 to vary thespring resistance to the tilting action. When plate 23 is tilted thereis a slight rectilinear sliding action of legs 54 and 56 in the members40 and 42, but the set screws 58 hold the legs 48 and 50 fixed.

The construction of FIG. 2 is the same as above described except thatthe supporting ears 20, 22, 3t) and 32 are omitted, and this provides adifferent spring action. The tilting plate 6% in FIG. 2 is supporteddirectly on the springs so that tubular members 62 receive legs 64 ofsprings 66 and the bosses 68 receive legs 7t} but in this case thebosses are secured in fixed position and cannot rotate. The position ofthe leg '70 can be adjusted in fixed bosses 68 and held there by the setscrew 72.

However, due to the lack of an axis of tilt for plate at the action isthat this plate tends to rock or tilt on an indeterminate axis locatedadjacent or in the coil at the closed ends of the U-shaped springs 66,rather than on a diametrical axis as defined by the pins 34.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

l. A device of the class described comprising a base plate, a pair ofspaced mounting members on said base plate arranged generally centrallyat opposite edges thereof, said mounting members extending at rightangles thereto, a tilting plate, said base plate and said tilting platebeing generally similar in size and shape and the tilting plate lyingjust above the base plate in general conformance thereto, spaced ears onsaid tilting plate arranged generally centrally at opposite edgesthereof and extending downwardly into and in conformation with saidmounting members, said ears and mounting members being pivoted togetherin pairs on a common axis,

and resilient means tending to maintain said tilting plate in parallelrelationship with respect to the base plate, said resilient meanscomprising a pair of upright U-shaped springs and means on therespective plates receiving the individual legs of the springs, theleg-receiving means on one plate providing for sliding motion of its legduring tilting of the tilting plate, and the leg-receiving means on theother plate including means to fix its respective spring leg againstsliding motion.

2. A tilting support comprising a swivel plate, a pair of spaced uprightU-shaped springs mounted thereon, a pair of bosses on the plate, saidbosses being apertured References Cited in the file of this patentUNITED STATES PATENTS White Oct. 17, Ayres Feb. 12, Larsen Mar. 9,Larsen Oct. 17, Larsen Aug. 2, Bottemiller Dec. 8,
